MSD window switch on an ls1?

Did a search but couldn't find much on it. I have a regular MSD window switch and am in the middle of wiring all of my nitrous stuff. Anyways my ? is can you wire an old school MSD window switch into LS1 stuff or does it need to be a digital style?

Please only people that have experience with this... Nitro Dave's, Harris, anyone?

The MSD with pills is not a problem. I've had one on my car for some time with no issues. There are more flexible units available but if that's what you have, you can wire it up and make it work.

Ditto. Wire it up and go. Works like a charm.

How do you guys have it wired up? Someone said you have to wire it up in a 4 cyl fashion (signal the ls1 gives off, had to wire my raptor shiftlight the same).

Yes it needs to be in 4 cyl. mode if coming off the tach reference signal at pcm.
